There have been many suggested solutions to this problem. And I'm in favour of the idea of building satellite cities in suburbs. The fresh air and beautiful scenery will attract people to leave the overcrowded city. With many people leaving the city, more space will be available for those remaining. We can find a lot of successful examples in other coun tries which solve the housing problem by building satellite cities.
Meantime, I don't think developing to the underground will help solve the problem. I can hardly imagine that people will like to live under the ground, withoul the sky and the sun. It will make people feel totally uncomfortable.
The building of satellite cities is a good way to solve the housing problem. It will not only relieve the burden on the big city, but also provide a much better environment for people to live. Of course, there is no perfect way to solve the problem. The housing problem is very complicated, involving many other problems such as traffic, you cannol rely on one way to solve the problem completely.
